DRY SMOKING-PIPE Specification of Letters Patent.

Patented March 9, 1909.

Application filed October 4, 1905. Serial No. 281,313.

To all whom it may concern:

Be it known that I, FRITZ MI'JLLER, a citizen of the Empire of Germany, and resident of Basel, in the Republic of Switzerland, have invented certain new and useful Improvements in Dry Smoking-Pipes; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a tobacco ipe having a grating inserted in the bowl, w ich with two parallel longitudinal erforations in the stem serving respectively lor smoke and for saliva. The saliva passage is below the smoke assage and its front end is a short distance elow the bottom of the hollow space of the pipe bowl.

Various attem ts have been made to prevent the nicotin om passing to the mouth of the smoker with the smoke, and to prevent the lower portion of the tobacco from becoming saturated with moisture and to prevent the nicotin from clogging the smoke passage, and it has been sought to remedy one or more of these objections by providing a grating in the bowl, and a saliva space or receptacle below. the bowl, and I therefore do not claim any such arrangement broadly, but only as set forth in the appended claims.

The accompanying drawing shows by way of example two constructions according to this invention.

Figure 1 shows the first construction in longitudinal section, Fig. 2 is a cross section on the line X-X of Fig. 1, Fig. 3 is a cross section on the line Y-Y of Fig. 1, Fig. i a cross section on the line Z-Z of Fig. 1

' through the bottom portion of the bowl.

Fig.5 is a longitudinal section showing a modified form.

In the example illustrated in Figs. 1 to 4 a rating c is inserted into the hollow space of the bowl in such manner that it cannot turn. it is rovided at its under side with a tube 1) whic 1 passes through the bottom of the ipe bowl and is provided with a longitudinal slot, as shown in Figs. 1 and 4.; at the lower extremity, and as shown in Fig. 1, it is provided with a screw thread and closed by a suitable screw cap 7:.

Below the usual smoke passage 0 which opens into the bowl under the grating a, but a ove the bottom of the hollow space of the bowl, the pipe is provided with another passage d for saliva parallel to the former, but of a slightly larger size. The two passages c and d merge into a common chamber e into which projects the union portion f of the mouthpiece g. The front end of the saliva passage (1 is below the bottom of the hollow chamber of the bowl and communicates with the longitudinal slot of the tube 1) connected to the grating a, the said tube b thus. establishing communication between the saliva passage (1 and the hollow space of the bowl.

' It is well known that the moistening of the tobacco in the bowl is unpleasant, and it oc curs not only in the case of inexperienced smokers who secrete much saliva, but even when the pipe is used 111 a very careful manner, owing to the fact that the tobacco burns Water 1s formed by condensation and, in pipes which are not provided with a grating, settles in the tobacco. Moist tobacco of course resists combustion and this is manifest by a hissing noise. In ordinary tobacco pipes a fairly considerable portion-of the tobacco introduced in the pipe must be thrown away unburned, thus be ng wasted, and the sucking in of the water of condensation and of the juice formed by the saliva of the smoker is very unpleasant and unhealthy. As in the tobacco pipe described the rating (t is arranged a short distance above t e bottom of the hollow chamber of the bowl, the tobacco can never become moist. The condensed water escapes through the longitudinal recess of the tube 12 into its interior and collects at the bottom end of this tube. Saliva emitted by the smoker passes to the same place through the passage (1-. Even if the whole juice were drawn in during smoking, it could not'pass into the stem as the chamber e would intercept it and as the union piece f does not reach to the bottom of the said chamber c.

in the construction illustrated in Fig. 5, a is again the grating inserted into the bowl, 0 indicates the smoke passage opening into the slowly and bowl under the grating, d the saliva passage,

narrow connecting passage i leading to the front end of the passage (1, so that the condensed water can flow away.

Having now particularly described and ascertained the nature of my said invention,

and in what manner the same is to be erformed, I declare that what I claim and desire to secure by Letters Patent is:

1. A dry smoking pipe consisting of the bowl, a grating in the same by which it is divided into an u per compartment for tobacco and a lower ho low space for smoke drying, a special saliva assage in the stem communicating with t c said hollow space in the bowl below and separate from the smoke passageof the stem, both of said passages communicatin with the mouth-piece passage, substantially as described.

2. A dry smoking pipe consisting of the bowl, a grating in the same by which it is divided into an up er compartment for tobacco and a lower hollbw space for smoke drying, a tube connected at its upper end to the grating and having a longitudinal slot at that I l i g ing through the said hollow space and through the bottom of the bowl and closed at its lower extremity, a special saliva passage in the stem below the bottom of the bowl opening into the said longitudinal slot of the said tube and thus communicating with the said hollow space of the bowl below and separately from the smoke passage of the stem,

both of the said passages communicating with the mouth-piece passage, substantially as described.

In testimony whereof I have 'aflixod my signature, in presence of two witnesses.

FRITZ MULLER.
